Empirical directional wave spectra for computer graphics
Christopher J. Horvath · 2015
In this paper, we describe the practical application of several empirically-based, directional ocean wave spectra for use in the Fourier synthesis of animated ocean height fields. We use the Texel MARSEN ARSLOE (TMA) empirical model for the non-directional component of the wave spectrum, and compare a selection of empirically-based directional spreading functions. Additionally, we introduce a novel, normalized parameter called "swell" which modifies the directional spreading to produce wavelength-dependent elongation of waves into parallel wave trains.
